An alias config is a pure redirect with no backend of its own, so the
capabilities listing described it from its stub: no capabilities, no
modalities, and the default 4096 context_size. Clients that size their
context budget from this endpoint (nib, for one) then compacted every
turn against a model that really serves 100k.
Resolve the alias and report the target's capabilities, modalities and
context_size under the alias's id. A dangling or chained alias now
reports no enrichment instead of defaults no model runs with.
